E27 high power LED bulb is a sort of LED bulb which utilizes high power LED as light source. It is made of aluminum alloy profile, PC or glass cover, and stainless steel E27 base. These materials ensure it heat dissipation, anti-impact and corrosion-resisitant. E27 high power LED bulb provides a innovative designed circuit to fulfil higher requirements. Using capacitor to replace traditional inductance transformer, the driver of this light will be more stable and longer life. Moreover, compared with halogen lamp and incandescent lamp, the competitive benefits of E27 high power LED bulb can be listed as below: (1)energy-saving, Environment friendly; (2)long lifespan; (3)anti-moisture, no glare, no strobe light; (4)easy installation, wide lighting angle, anti-dust / prevent from electricity shock. Substituting for halogen bulbs, this LED bulb can be used as lighting and decoration at places such as home, market, office, say, as localized lighting for the murals, the corridor and the stairway, and as lighting and decoration for display cabinets in the sales field.
